In the digital age, effective communication is paramount and for many of us who manage WordPress sites, email deliverability is a critical aspect of our online strategy. When we send emails from our WordPress sites, whether they are newsletters, notifications, or transactional messages, we expect them to reach our recipients’ inboxes. However, the reality is that many emails end up in spam folders or are simply not delivered at all.
This phenomenon can significantly impact our engagement rates and overall success. Understanding the intricacies of email deliverability is essential for us to ensure that our messages are seen and acted upon. As we delve into the world of WordPress email deliverability, we must recognise that it is not merely about hitting the “send” button.
A multitude of factors influences whether our emails land in the inbox or the dreaded spam folder. From technical configurations to content quality, each element plays a role in determining our email success. By exploring these factors and implementing best practices, we can enhance our email deliverability and foster better communication with our audience.

Why WordPress emails end up in spam
Several factors contribute to the unfortunate reality of our emails being marked as spam. One of the primary culprits is the reputation of our sending domain. If our domain has a history of sending spammy content or has been blacklisted, it can severely hinder our email deliverability.
Email service providers (ESPs) use complex algorithms to assess the reputation of sending domains and a poor reputation can lead to our emails being filtered out before they even reach the recipient’s inbox. Another significant factor is the content of our emails. Certain keywords and phrases can trigger spam filters, causing our carefully crafted messages to be flagged as unwanted.
Additionally, the frequency and volume of our email sends can also raise red flags. If we send too many emails in a short period or if our engagement rates are low, ESPs may interpret this as spammy behaviour. Understanding these factors allows us to take proactive measures to improve our email deliverability.
Configure WordPress to send mail properly
To enhance our email deliverability, we must first ensure that our WordPress site is properly configured for email delivery. This involves several technical steps that can significantly impact how our emails are perceived by ESPs. One of the first steps we should take is to verify that our site is using a reliable hosting provider that supports email functionality.
Some hosting providers may have restrictions or limitations that can affect our ability to send emails effectively. Additionally, we should consider using an SMTP (Simple Mail Transfer Protocol) plugin for WordPress. SMTP plugins help us send emails through a dedicated server rather than relying on the default PHP mail function, which can often lead to deliverability issues.
By configuring an SMTP plugin correctly, we can improve the chances of our emails reaching their intended recipients and reduce the likelihood of being marked as spam.
Use a proper email sending service
While configuring our WordPress site for email delivery is essential, partnering with a reliable email service provider (ESP) can take our email deliverability to the next level. An ESP offers robust infrastructure and tools designed specifically for managing email campaigns, ensuring that our messages are delivered efficiently and effectively. By leveraging an ESP, we gain access to features such as advanced analytics, list management and automated workflows that can enhance our overall email strategy.
Moreover, reputable ESPs have established relationships with major ISPs (Internet Service Providers), which can significantly improve our chances of landing in the inbox rather than the spam folder. They often employ best practices for email authentication and provide support for implementing essential protocols like SPF, DKIM and DMARBy choosing a reliable ESP, we not only enhance our email deliverability but also streamline our communication efforts.
Set up SPF, DKIM and DMARC
Email authentication protocols such as SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail) and DMARC (Domain-based Message Authentication, Reporting & Conformance) play a crucial role in improving our email deliverability. These protocols help verify that the emails we send are legitimate and not forged or spoofed by malicious actors. Implementing these protocols can significantly enhance our sender reputation and increase the likelihood of our emails reaching their intended recipients.
SPF allows us to specify which mail servers are authorised to send emails on behalf of our domain. By setting up an SPF record in our domain’s DNS settings, we provide ISPs with a way to verify that incoming emails from our domain are legitimate. Similarly, DKIM adds a digital signature to our emails, allowing recipients’ servers to confirm that the message has not been altered during transit.
Finally, DMARC builds on SPF and DKIM by providing instructions on how to handle unauthenticated emails. By implementing these protocols, we establish trust with ISPs and improve our overall email deliverability.
What the records look like
All three are DNS TXT records added at your domain registrar or DNS host (often the same place you manage your domain). Replace yourdomain.com.au and the provider values with your own.
SPF lists the servers allowed to send mail for your domain. One record only; if you already have one, add the new provider to it rather than creating a second.
Name: @ Type: TXT Value: v=spf1 include:_spf.google.com include:sendgrid.net -all
DKIM adds a cryptographic signature so receivers can verify the email was not altered. Your email or SMTP provider gives you the exact selector and value.
Name: s1._domainkey Type: TXT Value: v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC... (provided by your sender)
DMARC tells receivers what to do when SPF or DKIM fail and where to send reports. Start with monitoring, then tighten to quarantine or reject once the reports show only legitimate senders.
Name: _dmarc Type: TXT Value: v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com.au; pct=100
After adding them, send a test from your contact form to a Gmail address, open the message, choose “Show original” and confirm SPF, DKIM and DMARC all show PASS. Free checkers such as MXToolbox and Google Postmaster Tools will show the same result and flag typos. Gmail and Microsoft now reject or junk mail from domains without these records, so this step is not optional for a business that relies on form enquiries.
Monitor your sending reputation
To maintain high email deliverability rates, it is essential for us to monitor our email reputation regularly. Various tools and services are available that allow us to track metrics such as open rates, click-through rates, bounce rates and spam complaints. By analysing these metrics, we can gain valuable insights into how our emails are performing and identify any potential issues that may be affecting deliverability.
Additionally, we should keep an eye on blacklists that may affect our domain’s reputation. If we find ourselves on a blacklist, it is crucial to take immediate action to rectify the situation. This may involve reviewing our sending practices, cleaning up our email lists, or reaching out to blacklist operators for removal.
By actively monitoring our email reputation and taking corrective measures when necessary, we can ensure that our emails continue to reach their intended audience.
Avoid content that triggers spam filters
The content of our emails plays a significant role in determining whether they will be flagged as spam or delivered successfully. To avoid common pitfalls that trigger spam filters, we should focus on crafting high-quality content that resonates with our audience while adhering to best practices for email marketing. This includes avoiding excessive use of promotional language or spammy keywords that may raise red flags with ESPs.
Moreover, we should pay attention to the formatting of our emails. Emails that contain large images without accompanying text or those that are poorly formatted may be more likely to be marked as spam. Striking a balance between engaging visuals and informative text is key to creating content that not only captures attention but also passes through spam filters successfully.
Build engagement and trust with recipients
Engagement is a critical factor in improving email deliverability. When recipients interact positively with our emails—by opening them, clicking links, or responding—we signal to ESPs that our content is valuable and relevant. To foster engagement, we should focus on building trust with our audience by providing consistent value through informative content and personalised communication.
Additionally, encouraging users to add us to their contact lists or mark us as “not spam” can significantly improve our sender reputation over time. We can achieve this by including clear calls-to-action in our emails and making it easy for recipients to engage with us further. By prioritising user engagement and trust-building efforts, we can enhance our email deliverability and create lasting relationships with our audience.
Check your sender score
Our sender score is a crucial metric that reflects our reputation as an email sender. It is calculated based on various factors such as complaint rates, bounce rates and engagement levels. A higher sender score indicates a positive reputation, while a lower score may suggest issues that need addressing.
Regularly checking our sender score allows us to gauge how well we are performing in terms of email deliverability. To improve our sender score, we should focus on maintaining clean email lists by removing inactive subscribers and ensuring that we only send emails to engaged users. Additionally, segmenting our audience based on their preferences and behaviours allows us to tailor content more effectively, leading to higher engagement rates.
By actively working on improving our sender score, we can enhance our overall email deliverability and ensure that more of our messages reach their intended recipients.
Troubleshooting deliverability problems
Despite our best efforts, we may still encounter email deliverability issues from time to time. When this happens, it is essential for us to troubleshoot effectively to identify the root cause of the problem. Common issues may include misconfigured DNS settings, problems with authentication protocols like SPF or DKIM, or even issues with the content of our emails triggering spam filters.
To resolve these issues, we should start by reviewing our DNS settings and ensuring that all necessary records are correctly configured. Additionally, testing different email clients and monitoring bounce-back messages can provide valuable insights into what might be going wrong. By systematically addressing these issues and making necessary adjustments, we can improve our email deliverability over time.
Transactional email needs different infrastructure
Most WordPress sites try to send mail using the web server itself. That is why order confirmations, form notifications and password resets so often vanish. Web servers are not mail servers: they lack sending reputation, usually are not authorised to send for your domain and frequently sit on shared IP addresses with poor reputations.
The fix is to route your site’s mail through a dedicated sending service via SMTP or an API. That gives you authenticated sending, established IP reputation, delivery logs showing what happened to each message, bounce and complaint handling and the ability to see when something is failing rather than discovering it weeks later.
SMTP versus an email API
SMTP is the standard protocol — simple to configure in WordPress with a plugin, works everywhere, adequate for typical volumes. API-based sending is faster, gives richer delivery data and better handling at higher volumes and is worth the extra setup for stores or sites sending in bulk.
Either way, the requirements are the same: authenticate the domain with SPF, DKIM and DMARC, send from a real address at your own domain and keep transactional mail separate from marketing mail so a campaign complaint cannot jeopardise your order confirmations.
Why it matters commercially
Undelivered transactional mail is invisible revenue loss. A customer who never receives an order confirmation contacts support or disputes the charge. An enquiry notification that lands in spam is a lead you never knew existed. Password resets that fail create support load and account abandonment. None of these appear in your analytics — which is precisely why they run undetected for months.
Practical checklist
- Route site mail through a reputable sending service rather than the web server.
- Authenticate the domain properly and monitor DMARC reports.
- Send from a monitored address, not a no-reply that discards replies.
- Test every form and checkout notification after any change to the site or DNS.
- Watch bounce and complaint rates and remove bad addresses promptly.
- Keep transactional and marketing sending on separate subdomains.
